WD5000AAKS-75YGA0 with a dead head
October 13th, 2011, 13:03
Heya all. Got this tornado in for a change it is not a board that troubles it.
On power up the drive spins and clicks then spins down. Tried a different board with patient rom - same.
Put native board to the donor - works. So not the board =)
Native board with native rom on patient drive, in PC3k started playing with heads. If i disable the head 3 the drive will NOT click upon recalibration attempt and calibrates fast , yet still will not ID for me ( sounds very healthy , just what i expect ) . The SA only gives access to first module which is "modules directory" and nothing else. Got a donor from the same family with a different model and swaped the heads ( read on deepspar forum that Jono was successful with smth like that case =) ) Donor is wd5000AAJS-00YFA0. With donor heads it clicks , and if i disable the head 2 it will calibrate with no ID and access to same "modules directory" only. Put the donor heads back - work 100 percent. What do u think is happening here? Physical SA problems? Or original heads are dead and donor heads not compatible so need more donors ?
PS forgot to mention i managed to read the SA tracks with original heads with no problems. But not the modules. Hmm now as i type it... Smart hot swap attempt incoming =))) Ty for help +)))

Donor is YF whilst patient is YG, I would imagine this to be a problem for compatibility?

YF vs YG is not an issue

If you are able to read tracks, you should have been able to read modules.

yeah but i am not =( Thats why ima here to be honest =) Out of the modules only the module 1 "module library" is read. Thats it. And today i was put on a burning project so didnt even have a chance to play with hot swaps yet.

Sounds like you have multiple issues -- probably a bad head and corrupt FW. if critical modules are damaged (e.g. 11), there is no chance it will passport even after you replace heads.
Hot swap is key to diagnosis -- to determine what heads and modules are bad, and to fix or replace them if that is possible.
Also, after you get drive spinning with hot swap (but with no ID), exit the utility and re-enter, loading module 01 that you got earlier (assuming it is good) before you check the modules. I'll bet you'll see a different result from when you check modules without doing that step . . .
Good luck!
